State Sen. Suzanne Bonamici of Beaverton has reportedly raised $600,000 in the first two months of the special congressional election in Oregon's 1st Congressional District.

Associated Press first reported the fundraising figure, which The Oregonian independently confirmed with a knowledgeable source. The sources did not provide information about whether the totals included any contributions from Bonamici herself.

Tualatin businessman Rob Cornilles, the leading Republican contender, put out the word through his campaign earlier this week that he had raised more than $500,000 for his campaign.

Bonamici, who faces competition in the Democratic primary from state Labor Commissioner Brad Avakian and state Rep. Brad Witt of Clatskanie, has been the only candidate to begin advertising on TV -- which is one sign that she holds a fundraising lead over her rivals.

The state senator won a crucial endorsement after starting her campaign in August from Emily's List, a fundraising network that supports Democratic women running for office.

The candidates are required to file financial disclosure reports with the Federal Elections Commission by Oct. 15.
